Regular rate of pay: calculate your hours and true rate

The formula, and why an agreement cannot change it

Many people assume overtime is computed on “what they earn per hour.” The FLSA does not say that: it says overtime is paid at **no less than time and one-half the regular rate of pay**, and the regular rate **is calculated**.

The formula the U.S. Department of Labor publishes fits on one line: **total compensation in the workweek (except the statutory exclusions) ÷ total hours worked in the workweek = the regular rate for that week**.

Note two things. First, **it is weekly**: the regular rate can change from one week to the next, because it depends on what you earned and the hours you worked that week. Second, DOL puts it bluntly: **the regular rate is based upon actual facts and cannot be circumvented by an agreement**. Signing a paper saying your overtime will be computed on the base rate does not change the math.

And it has a floor: **the regular rate may not be lower than the FLSA minimum wage** or, where applicable, a higher state or local minimum wage. If the regular rate comes out higher than the federal minimum, overtime must be calculated **using that higher rate**.

Earnings may be on a piece rate, salary, commission or another basis — in all those cases, DOL says, overtime **must be computed on the average hourly rate derived from those earnings**.

Add up your week's hours

The regular-rate math starts with knowing how many hours you actually worked. Add each shift, including ones that cross midnight, and see the weekly total and how many fall into overtime.

What goes in: a promised bonus is not a gift

The inclusion rule is broad: under the FLSA, the regular rate **includes “all remuneration for employment” paid to or on behalf of the employee**. The exclusions are those the statute lists, and it is **an exhaustive list** — not a general standard.

That is why a **nondiscretionary bonus goes in**. DOL defines it in reverse: a nondiscretionary bonus is one that **fails** the discretionary-bonus requirements, and it **is included in the regular rate**. Its examples are concrete:

• **Bonuses based on a predetermined formula**, such as individual or group production bonuses.
• **Bonuses for quality and accuracy** of work.
• **Bonuses announced to employees to induce them to work more efficiently.**
• **Attendance bonuses.**
• **Safety bonuses** — for example, days without incidents.

The bonus label decides nothing

DOL explains why those bonuses are nondiscretionary: **because employees know about and expect them**. Understanding how one is earned can create an expectation of receiving it regularly. And it adds the kicker: **the fact that the employer has the option not to pay the promised bonus does not make the bonus discretionary**.

In the other direction, a **discretionary** bonus is excluded **only if it meets all the statutory requirements**: that **both the fact of payment and the amount** are at the **employer's sole discretion at or near the end of the period**, and that it is **not paid according to any prior contract, agreement or promise** causing the employee to expect it regularly.

And the line that ends the hallway argument: **the label assigned to the bonus and the reason for it do not conclusively determine whether it is discretionary**. Calling it “discretionary” in the letter does not make it so if it fails the statute; the determination is made **case by case**.

One more, in case it comes up: **a discretionary bonus may not be credited toward the overtime compensation** the FLSA requires.

The three steps, with DOL's own numbers

DOL publishes the computation in three steps, and it works the same whether you are paid hourly, by piece, by day, by job, by commission or by salary.

**Step 1:** total compensation for the week (except the exclusions) **÷** total hours worked **=** regular rate per hour (which cannot be below the federal minimum). **Step 2:** regular rate **× 0.5** = half-time premium for each overtime hour. **Step 3:** that premium **×** overtime hours = overtime compensation due.

Why half and not time-and-a-half? Because **the straight time for those overtime hours is already counted in Step 1**. What remains is the half.

**DOL's example, with a nondiscretionary bonus.** A non-exempt employee earns **$10.00 per hour**, works **43 hours** in the week and receives a **$50.00 bonus** promised for helping produce a special order two weeks ahead of schedule. The math: $10.00 × 43 = **$430.00** straight time; $430.00 + $50.00 = **$480.00** total compensation; $480.00 ÷ 43 = **$11.16** regular rate; $11.16 × 0.5 = **$5.58** premium; $5.58 × 3 overtime hours = **$16.74**; total **$496.74**.

**Second example, with a shift differential.** An employee at **$15.00 per hour** plus **$1.00 per hour** evening differential, working **45 hours**, **30** of them on evening shifts, who also earns a **promised $100.00 bonus**. The math: $15 × 45 = **$675**; $1.00 × 30 = **$30** differential; $675 + $30 + $100 = **$805** total compensation; $805 ÷ 45 = **$17.89** regular rate; $17.89 × 0.5 = **$8.95**; $8.95 × 5 overtime hours = **$44.75**; total **$849.75**.

Look at what happened in the second one: **the differential and the bonus lifted the regular rate from $15.00 to $17.89**. That difference is exactly what is lost when someone computes overtime on the base rate.

What can be excluded

The exclusion list is statutory (29 U.S.C. § 207(e)) and DOL summarizes it in Fact Sheet 56A. These are the ones that show up most on a real pay stub:

• **Gifts and payments in the nature of gifts** on holidays or special occasions, **provided they are not measured by hours worked, production or efficiency**.
• **Payments for occasional periods when no work is performed**: vacation, holidays, sick leave and other paid time off — including when the employer fails to provide sufficient work (machinery breakdown, supplies that do not arrive, bad weather).
• **Pay for unused leave** (“buy-backs”) and pay when the employee works instead of taking leave or a paid holiday. If you work the holiday and are paid for hours plus the holiday payment, **that holiday payment is excludable** because it is not pay for hours worked.
• **Pay for bona fide meal breaks**, which are not hours worked — unless an agreement or established practice treats them as hours worked, in which case **they must be included**.
• **Reimbursement of business expenses** at actual or reasonably approximate amounts: supplies or tools, **cell phone plans**, professional organization dues, **credentialing exam fees** and travel expenses.
• **“Show-up” or “reporting” pay** when you are sent home early for lack of work, **provided it is infrequent and sporadic**.
• **“Call-back” pay** for unanticipated extra work, **provided the call-back was not prearranged**.
• **“Perks” with no connection to hours, services or performance**: on-the-job medical care, gym access, wellness programs, employee discounts, parking, **tuition payments** (employee's or a family member's) and adoption assistance.
• **Discretionary bonuses**, under the two-part test explained above.
• **Bona fide profit-sharing or thrift savings plans**, and **irrevocable employer contributions** to a trustee or third person under a bona fide plan for retirement, disability, medical expenses, hospitalization, accident, unemployment or legal services.
• **Premium pay for overtime the FLSA does not require** — for exceeding eight in a day, or normal hours, or for Saturdays, Sundays, holidays or rest days — when the premium is **at least time and one-half**; and those premiums **may be credited** toward FLSA overtime.

How this meets Puerto Rico law

The above is the **federal floor**: what counts as the regular rate and how overtime is computed under the FLSA. **When overtime is owed in Puerto Rico and at what multiple** is a different conversation — Act 379 of 1948 — and it is in our overtime and hours guide, including the currency warning about Act 41-2022, which was annulled.

Where this concept moves real money in Puerto Rico is in three situations we cover separately and that you can now read with the formula in hand. **One:** **service charges** distributed in restaurants and hotels — DOL says they are part of total compensation and **must be included in the regular rate** for computing overtime. **Two:** **commission salespeople**, where the regular rate comes from dividing total earnings by hours. **Three:** any job with a **shift differential** or a **production, attendance or safety bonus**.

And a scope warning so you use this precisely: the Wage and Hour Division's fact sheets are **guidance documents** summarizing the statute and the regulations (29 C.F.R. § 778.200-.225). If your case turns on a specific figure, ask for the computation in writing and get advice before signing any release.

What to check in the week you worked overtime

**One:** did you receive anything that week beyond your rate — a promised bonus, a differential, commissions, a service-charge distribution? If so, **that week's regular rate is not your hourly rate**.

**Two:** do Step 1 yourself. Add everything that goes in and divide by **the hours you actually worked**. Compare that number with the one payroll used for overtime.

**Three:** if the bonus covers several weeks — a quarterly goal, say — ask how it was allocated. A nondiscretionary bonus goes in; the question is into which weeks.

**Four:** if they tell you the bonus is “discretionary,” remember the two-part test: employer discretion **over both the fact and the amount**, and **no prior promise** making you expect it. The label does not decide.

**Five:** keep that week's pay stub. It is the document that proves the computation, and without it the conversation becomes an argument from memory.
